Update to newer Centos7 images

Browse Source 
Update to newer Centos7 images as announced at [1].

Changes included:
 * update to GA image
 * respect TMP_DIR for image working directory
 * use suffix-match rather than prefix-match to build RAW_IMAGE name
   to be more robust against weird names
 * partition layout work-arounds not needed any-more, all one
   partition.

Resulting image booted locally with kvm and virtualbox (after
conversion to vdi)
